I got a rather dusty Macintosh IIci (M5780) with no RAM or hard drive, marked by the eBay seller as "Powers On". I also purchased a Macintosh Color Display (M1212) which was "tested". I put in some memory from 1-800-4MEMORY on eBay marketed as a 32MB kit (16MB x2) for Macintosh IIci. I bought two of those kits. I put in a 160MB Apple branded IBM hard drive that I had used, tested, and installed a fresh copy of System 6.0.8 through an external enclosure hooked up to a Macintosh SE FDHD (dual floppy).
I had to use a trick from http://shobaffum.com/iici/faq.html#11:
When I turn it on I hear the hard drive spinning up, and the IIci fans seem to run, but it doesn't read my known-good System 6 boot floppy (tested on the aforementioned SE). The floppy drive is probably dusty. Nothing displays on the monitor. I don't seem to hear a startup chime, though I might have once with all 4 16MB SIMMs installed.
Any ideas as to what might fix it?
Also, the forum says I originally posted at 7:53 AM! Good for System 7.5.3!
P.S. I have tried with both 2 and 4 SIMMs installed.

<< Does anyone know if these 2 supplies are compatible, I need to replace the [iIc]x power supply and I may be able to get a [iI]ci supply. The main problem is that the computer does not turn on.>>
Before you buy a new power supply, try this: Get ahold of a cheap "power strip" with an on/off switch. Plug the IIcx into the power strip. When the IIcx is off, leave the power strip switch in the OFF position. When you're ready to boot up, reach down and flip the power strip on. Wait a few seconds, and press the keyboard power-on button. When it's time to shut down the computer, go through the normal shutdown procedure. After the IIcx "turns itself off", reach down and flip the power strip to OFF. Try this - you may be VERY pleasantly surprised with the results...
The theory is that the +5 V charge is still there briefly when you send current to the power supply. If you can start up the Mac quickly enough, you won't need the trickle charge while it's running.
